It would be a mistake to see this list as _dead_; it merely has a _very_
slow heartbeat. ;-)

The Rex is going to remain in use by some simply because it's sufficiently
powerful for their purposes; and others are going to be keen on it for much
the
same reason as there are people who are keen on old 8-bit personal
computers.
(Indeed, the Rex 6000 _is_ an old 8-bit personal computer.)

People in the former category will need this list occasionally. People in
the
latter category will also want this list, but will presumably not have a lot
of
time to devote to a peculiar hobby.
